  As 'time(0) | getpid()' will have a lot of duplicated value. It is not a
  expected behavior. We expect different value for the seed when when run
  it in many times.

  So this patch will left shift the getpid() and add to time(0). That
  avoid duplicated value.

  Test command is like:
  % RUN=0; while [ $RUN -lt 10000 ]; do
  tools/gen_eth_addr; RUN=$(($RUN+1)); done | sort | uniq | wc -l
  10000

  This patch is incorporated with suggestions made by Wolfgang Denk and Andreas
  Bießmann. Thanks them a lot.

  Replace random()/srandom() use with rand()/srand() to support
  compilation with the mingw toolchain. The rand()/srand() functions are
  generally more common and are functionally equivalent to the original
  random()/srandom() calls.
